The value of b is -9. The equation of the line is y = 3x - 9
Answer:
D y= 81
Step-by-step explanation:
Since the triangles are similar, the ratios of similar sides must be equal.
30/54 = 45/ y
We can use cross products
45*54 = 30*y
2430=30y
Divide each side by 30
2430/30 = 30y/30
81 =y
Firstly, change 30% into a decimal then multiply by $48 to get 30%
30%=0.3
$48*0.3=14.14 then substract 14.4 from $48 to get the discount.
$48-14.4= $33.6.
so, the discount is $33.6
The scientific notation is used to write very large or very small numbers into simplified version of the number. That is raised to 10^x
The formula to divide the numbers written in the solution.
All the best! Ace!
